Honeywell HA40 technical manual System Configuration Menus, Standard / Optional Relay Setup Menus

Unity Gain may be used at anytime to cancel incorrect calibrations and start again. Unity means Offset = 0.00 and Gain = 1.00.

2.3.1 Standard / Optional Relay Setup Menus

The menu shown in Figure 2-8 allows configuring of both the standard Relay 1 & Relay 2 motherboard relays and the six optional relays on the 10-0222 discrete relay option PCB. Both standard and optional relays are programmed in this menu. Select the relay to be configured by pointing the arrow at the top menu item and pressing Edit. The field will scroll through all eight possible relays (2 standard and 6 optional).

•Fault, Alarm 1, Alarm 2, Alarm 3 menus (Figure 2-8) offer additional “voting” flexibility by controlling the channel alarm combinations that will trip the selected relay. Each Votes entry requires the specified quantity of that alarm to be active before this relay activates. As illustrated in Figure 2-24 Standard Relay 1 activates when any 2 channels have Alarm 1 conditions, PLUS, any one channel has an Alarm 2 condition. Fault Votes and Alarm 3 Votes values are 0 therefore Fault and Alarm 3 conditions will not affect this relay.

•Failsafe set for YES causes this relay to be energized when its voting requirements are false (no alarm condition) and de- energized when the alarm vote requirements are true. The primary benefit of failsafe is loss of power places the relay contacts into the alarm condition.
